Tire blocks vary in height from
below 6" to above 10" with most approximately 8" high. You
can specify the height of the blocks if you want smaller or larger steps
in your mounting block.

Weight

A typical 8" tire block
weighs approximately 100 pounds.

Stability

When the tire blocks are
stacked the shear weight keeps them in place. When stacking higher than
24" additional stability is suggested by driving a 2" pipe
through the center of the block into the ground below or driving large
staples/rods directly through the blocks.
